BIAS-1 BIAS-2 FUNCTION DESCRIPTION
0 0 Full bias mode Amplifiers ON with lowest distortion possible (default state)
1 0 Mid bias mode Amplifiers ON with power savings with a reduction in distortion performance
0 1 Low bias mode Amplifiers ON with enhanced power savings and a reduction of performance
1 1 Shutdown mode Amplifiers OFF and output has high impedance
(1) Logic pins should not be left floating and should be held at a logic-0 or a logic-1 by external circuitry.
